 are somewhat fractured or corroded away. No distinctive 

 characters were noticeable in the material at hand. 



Beak. — No. 12532. The fragment of the upper mandible pre- 

 served is sufficient to show its true stork-like nature and to 

 make it almost certain that there was no recurvature such as 

 appears in Jabiru. The most liberal restoration indicates a maxi- 

 mum length of 210 mm. The cross-section in the nareal region

is almost an equilateral triangle. The nostrils are slit-like with 

 edges overhanging above and rounded in below; the proximal 

 and distal extremities are smoothly rounded ; there is no inter- 

 nareal septum. The buccal surface of the beak is closed over 

 entirely and marked to a point slightly beyond the nares by a 

 double groove down the median line, and from this point on by 

 a shallow median depression. The fragment corresponds very 

 closely with the same region in Euxenura. It is slightly larger, 

 whereas the limb bones appear smaller and less robust. The 

 ridge of the culmen is sharper and the nostrils do not dilate 

 from base toward tip of beak. The profiles are very closely 

 similar.
